Abstract


A simple detachable, inexpensive, acrylic four-arm olfactometer, which provides a controlled odour plume for conducting free choice tests and a simple wind tunnel set up, which can be used to track and measure upwind movements of specific odours are described. Both devices were tested with Trichogramma chilonis Ishii, the egg parasitoid of rice leaf folder, Cnaphalocrocis medinalis Guen in the laboratory. These devices can also be used for monitoring the responses to olfactory cues of other small insects as well.
